Optimas do not seem to run asynchronously

[delaossa]

Some tests such as this: https://github.com/optimas-org/optimas/blob/main/tests/test_ax_model_manager.py
do not seem to run asynchronously when run_async=True is passed to the Exploration object.

Thanks for reporting @delaossa , we'll investigate this.

I have been running optimas asynchronously with (fbpic) simulations that run on the GPU with no problems.
I wonder if the issue mentioned above is something particular of the FunctionEvaluator, which does not run with mpi.

Ha, good catch. I suspected that that could be the case. I don't know right now why the FunctionEvaluator is behaving differently, but it is indeed probably the reason.
